The diploma thesis presents the development and production of an independent system designed to demonstrate the operation of solar cells and photovoltaic modules. The system contains a dual-axis solar tracker that is easy to use and has the ability to adjust the sensitivity of sensors, a battery that serves as a power source, and a measuring circuit that displays the charging current and the battery voltage via the microcontroller on the LCD screen.
In the theoretical part, solar cells, solar trackers and other key elements of the system are presented. Next section presents the production of individual sets, divided into hardware and software. Hardware part describes the production of sample photovoltaic modules and the tracker design, including the design of the sensor module and the control of the stepper motors. Software part describes the tracking algorithm and the source code.
